NFC function revealed: beyond payment, discover more practical ways

NFC has always been one of the hot topics. Therefore, in order to cater to the public's interest, the editor decided to bring you relevant content about NFC. The following is a detailed introduction.

1. Purpose of nfc

1. NFC one-touch transmission

One-touch transfer means file data transfer, which is an advantage of the NFC function. NFC transmission speed is much faster than traditional Bluetooth transmission. On Huawei smart terminals, this feature is fully demonstrated. For example, two Huawei phones can transfer files with just one touch; another example, a Huawei phone can quickly transfer files to the computer by just touching the NFC area of a Huawei laptop.

2. NFC one-touch connection

In the past, connecting two smart devices was usually achieved through Bluetooth or WIFI, such as connecting a Bluetooth speaker or connecting a smart router. However, if both smart devices and mobile phones support the NFC function, it will be more convenient to connect them through NFC. We only need to touch our smart devices with our mobile phones to quickly connect them.

3. NFC electronic ID card

The NFC function of the mobile phone can also read ID card data and enter the identity information into the mobile phone to turn it into an electronic ID card. Although electronic ID cards are currently only on trial in some areas. For example, the electronic ID card of Huawei mobile phones can be used in some hotels in Shenzhen, this is the future trend.

NFC mobile payment

When it comes to mobile payment, most people think of WeChat Pay or Alipay. But in fact, mobile payment can also be realized through NFC function, such as Huawei Wallet. Huawei mobile phones read bank card data through NFC. After binding the bank card, you only need to touch the mobile phone to the POS machine to complete the payment, which is faster than scanning a QR code to pay.

5. NFC bus card

Most people take buses or subways to work every day, and they use bus cards at this time. However, it is not convenient to carry a physical bus card, and sometimes you forget to bring it. NFC bus card solves this problem. After the NFC bus card is activated on your mobile phone, you can ride on the bus or subway by just touching the card machine.

6. NFC access card

Many communities and companies use access cards to enter and exit, but the cards are inconvenient and easy to lose. Mobile phone NFC access control cards solve this problem. By reading the access card data through the NFC function of the mobile phone, the mobile phone becomes a virtual access card, and you can enter by simply touching the card machine at the gate.

7. NFC car key

You can unlock the vehicle through your mobile phone, which is a very cool feature. Currently, only some BYD models support the mobile phone NFC car key function. Simply hold your phone close to the car's signal receiver to unlock the vehicle. The mobile phone does not need to be connected to the Internet and can unlock the car regardless of the battery level, eliminating the trouble of carrying a remote control or keychain.

2. NFC business characteristics

In recent years, NFC technology has attracted much attention, and businesses based on NFC technology have penetrated into every aspect of people's lives.

Services based on NFC technology are mainly based on the 13.56MHz frequency and have short transmission distances. Information transmission is triggered and takes a very short time, requiring rapid processing.

(1) Short: The communication distance is short, generally within 10cm.

(2) Frequency: NFC applications are gradually penetrating into people's daily lives, and their use will become more and more frequent.

(3) Fast: Information is transmitted quickly and needs to be processed quickly.

Due to the short distance, frequency and speed of NFC technology, there are some limitations for NFC services.

(1) Regional limitations: NFC technology operates over a short distance, and each region establishes an independent business system.

(2) Industry limitations: Various industries lack unified standards and interoperability issues exist.

(3) Business diversity: NFC business is a bridge between users' real life and virtual life.
